RIVETING DEVICE.

Speccation of Letters Patent.

Patented Nov. 21, 1905.

Application filed January 30, 1905. Serial No. 243,272.

To all whom t may concern:

Be it known that I, FRANK SHEPPARD, a

` citizen of the United States, and a resident of Alhambra, Illinois,'have invented certain new and useful Improvements in Riveting Devices, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in riveting devices; and it consists of the novel features herein shown, described, and claimed.

In the drawings, Figure 1 is a perspective of a riveting device embodying th'e principles of my invention. Fig. 2 is a vertical central section on the line 2 2 of Figs. 1 and 4 and looking in the direction indicated by the arrows. Fig. 3 is a sectional detail on the line 3 3 of Fig. 1. Fig. 4 is a horizontal section on the line 4 4 of Fig. 1.

Referring to the drawings in detail, the frame of my improved riveting device comprises a casting substantially in a rectangular form, said casting having a rivet-set chamber 5, vthe lower end of which is reduced in size to form a washer-set 6, having a central opening to receive the point of the rivet-set. There is a rivet-chamber 7 arranged parallel with the chamber 5. The punch-holders 8 and 9 extend from the rivet-chamber and have openings in vertical alinement to reits handle extending downwardly through the punch-holders 8 and 9 and with its point below the upper end of the casting.

Recesses and 16 are formed in the outer faces and upper ends of the side walls of the rivet-chamber. The cover 17 is adapted to close the rivet-chamber 7. An arm 18 extends from the cover over the punch 14 to hold the punch in place, and spring-arms 19 and 20 extend from the sides of the cover downwardly, the lower ends of said arms being bent inwardly to snap in the recesses 15 and 16 to hold the cover in place.

Vhen it is desired to use the device, the rivet 21 is inserted through the straps 22 and 23, the washer 24 is placed in position upon the rivet, and the riveting device is placed in position with the washer-set 6 upon the washer and the rivet extending into the rivet-set opening against the lower end of the rivet-set 11. Ahammer is used to strike the ledge. 10 to drive the washer down upon the rivet. Then the hammer is operated to strike the rivet-set 11 and upset the point of the rivet. The stock of rivets is carried in the chamber 7.

I claim- 1. In a riveting device, a casing forming a rivet-chamber, punch-holders extendingfrom the exterior of said rivet-chamber and having alined openings, and a cover closing the rivet-chamber and arranged so that one of its ends projects freely in alinement with said alined punch-holder openings for holding the punch in position when it is in the openings of said punch-holders.

2. In a riveting device, a casing forming a rivet-set chamber, and having a reduced lower end to receive the point of the rivet; a rivet-set having its lower end reduced in diameter and mounted in said chamber; a washer-set 6 projecting at the lower end of said casing, and a hammer-ledge 10 projecting laterally at one point only on the upper end of said chamber.

In testimony whereof I have signed my name to this speciiication in presence of two subscribing witnesses.

FRANK SHEPPARD.
